Cloud Migration 101
- Cloud computing is a commonly used term, especially in the tech world. Many Internet users regularly use cloud-computing services without knowing. Simply put, cloud computing is a technology that allows remote access to shared computing resources like servers, storage, and applications. This is made possible without interacting with the service provider. Through cloud computing you can do tasks that you usually do on your computer using any computer provided you have Internet access. Web mail is an example of a cloud-based resource. This service allows users to access their emails from any Internet-enabled device instead of using an email client and downloading mails onto a hard drive.Best Practices When Migrating to the CloudSecurity and AccessSome of the factors that people consider when migrating to the cloud include data management, security, and access. Cloud computing provides a centralized security access tool such as forefront plug-ins on the active directory. Although cloud computing is considered safer than other data management solutions, it is only as safe as the applications that run in it.AvailabilityTraditional enterprise servers often feature huge memory capacity and mega processors that are designed to make data highly accessible and available. However, many applications show signs of better performance and availability through underlying deployment. The application design has various single point weaknesses that are not usually dealt with during migration. For the data management infrastructure to be effective, the application design should be addressed for multiple points of failures. Although the lift and shift approach may be financially appealing, it is important to consider other options including re-factoring and re-designing. Monitoring Alerts This represents the workflow of most of the production and operation support team. Some centralized tools conduct server monitoring and have a custom solution that alerts the appropriate team and stakeholders. The application is often unaware of the support structures required to keep it operational. DNS and IP Management Database as a service enables users to access legacy applications through internal intranet URL. In a traditional server, users conducted DNS management in a centralized server cluster. This means that you can even run out of IP addresses. However, migrating to the cloud makes it easier to perform DNS entry rewiring. Nevertheless, this requires careful planning and network design, especially in a hybrid cloud setup. Server Sprawl Deployment models found in most of the enterprises that use database as a service are designed to prevent server sprawls. Increased utilization and lack of management tools are factors that lead to server sprawls. The tooling features available in public clouds may be quite different from those of hybrid or private clouds. It is common for organizational team structures to implement legacy deployment models to the cloud. Licensing Licensing problems also contribute to server sprawls. Although multiple applications can share the same license, this scenario would involve a substantially different cost model when moving to individual servers, regardless of how small the servers are. Consider re-platforming to open source tools in case this causes a legacy deployment model on the applications. Certificate Management and Disaster Recovery Most enterprise applications have centralized DR plans and processes put in place. Cloud migration offers a chance to tier applications depending on the service levels, which in turn develops application specific deployment models. Legacy applications differ from cloud-based applications. Therefore, a simple shift to the cloud would render applications unstable or unusable. This can be solved by re-factoring which is needed to fully leverage the cloud. New deployment design is enough to address such challenges. Replicating the legacy architecture in the cloud or replicating legacy servers and cluster deployment models in private clouds is not recommended. Advantages of Hybrid Cloud Computing Hybrid clouds just like public clouds have their uses and advantages. They are fit for purpose, which makes them preferred by many businesses. Because businesses have various sets of needs, it is hard to find a one-size-fits-all cloud computing service and that is where hybrid clouds come in. Hybrid clouds meet the required needs of a business by matching the right solution to the right job. They minimize tradeoffs and slow down technical barriers to ensure improved performance and maximum benefits. Public clouds have proved that they can work well in tests and development, startups, and in handling peaks in web traffic. The disadvantage lies in the tradeoffs that can occur even in mission critical data security. Public clouds that operate primarily on dedicated gear help to enhance data security, but limit applications with a minimal shelf life. Connecting dedicated resources to cloud components can significantly reduce IT costs. Businesses can take advantage of the benefits of hybrid cloud computing to improve cost efficiency and reduce their overall cost of ownership. One of the most important aspects of any business is protecting sensitive client details. With hybrid cloud computing, you are assured of improved security as businesses address compliance and security concerns. Cloud computing comes with many benefits, especially for businesses. This is why many businesses are moving to the cloud. However, it is important to plan and prepare for the move.
